FIG. 2 is a perspective view of a dock shelter module in a closed state, and FIG. 3 is a perspective view of a dock shelter module in an open state according to the first embodiment of the present invention.

2 and 3, the dock shelter module 10 according to the first embodiment of the present invention is disposed on one side of the warehouse to serve as a passage connecting the inside and the outside of the warehouse. Therefore, when the logistics loaded in the loading box of the transport vehicle 20 is loaded and unloaded into the warehouse, it becomes a connection passage that is directly transferred to the warehouse through the dock shelter.

The dock shelter module 10 according to the first embodiment of the present invention maintains the temperature inside the warehouse by preventing the cold air or hot air inside the warehouse from leaking out during the loading and unloading process, and contaminants outside the warehouse The upper frame 110, the side frame 130, the lower frame 150, the first gate 210, the second gate 220, and the air curtain forming part 300 may be configured to prevent inflow into have.

The upper frame 110, the side frame 130, and the lower frame 150 may form an upper and lower space between the loading box of the transport vehicle and the warehouse. The side frame 130 is coupled to both sides of the upper frame 110 to extend in the longitudinal direction, and the lower frame 150 is coupled to the lower end of the side frame 130. That is, one side of the side frame 130 is coupled to the upper frame 110 and the other side is coupled to the lower frame 150. The dock shelter module 10 according to the first embodiment of the present invention may form an upper and lower space, which is a passage through which logistics is moved, by the upper frame 110, the side frame 130, and the lower frame 150.

The upper frame 110, the side frame 130, and the lower frame 150 may further include bumpers (not shown) to alleviate a collision. The bumper may play a role of preventing damage by absorbing the collision when the transport vehicle 20 approaches and collides. The bumper may further include a sensor (not shown) that recognizes when the transport vehicle 20 approaches and transmits a signal alarm when approaching within a preset distance.

In the present specification, the outer side of the warehouse is defined as the front of the upper and lower space, and the inner side of the warehouse is defined as the rear of the upper and lower space. The first gate 210 and the second gate 220 may be coupled to the upper frame 110 to open and close the upper and lower spaces. The first gate 210 may be provided in front of the upper and lower spaces to open and close the outside of the warehouse and the upper and lower spaces. Meanwhile, the second gate 220 may be provided at the rear of the upper and lower spaces to open and close the upper and lower spaces and the interior of the warehouse.

The air curtain forming unit 300 is a device for forming an air curtain by injecting air into the upper and lower spaces, and may be installed between the first gate 210 and the second gate 220 on the lower surface of the upper frame 110. .

During the loading and unloading operation, the gate is open, so there is a problem in that cold air inside the warehouse flows out or pollutants from outside flow into the inside. By forming the air curtain in the air curtain forming unit 300, it is possible to block the outflow of cold air inside the warehouse and prevent the inflow of contaminants outside the warehouse.

In addition, the dock shelter module 10 according to the first embodiment of the present invention includes a security module 400 that requests input of pre-stored user information in order to open the first gate 210 and the second gate 220. It may further include, and when the user inputs user information, date and time information regarding the opening and closing of the first gate 210 and the second gate 220 together with the user information may be transmitted to and stored in a separate server. have. To this end, a separate management server connected to the security module 400 and wireless communication may be provided, and a detailed description thereof will be omitted as a prior art.

By providing such a security module 400, it is possible to enhance security and effectively manage inventory by storing the loading and unloading work history.

In addition, when the first gate 210 and the second gate 220 are closed in order to close the up and down space after the loading and unloading operation is completed, the second gate 220 is closed more than the speed at which the first gate 210 is closed. The speed can be set quickly. This is because the second gate 220 opens and closes the interior of the warehouse and the upper and lower spaces, so it is necessary to quickly close the second gate 220 after completion of the loading and unloading operation in order to prevent the cold air inside the warehouse from leaking to the outside. On the other hand, since the first gate 210 opens and closes the upper and lower spaces and the outside of the warehouse, the moisture in the upper and lower space needs to be sufficiently discharged to the outside of the warehouse, so that the first gate 210 is less than the speed at which the second gate 220 closes. The speed at which) is closed can be set slower.

Since the second gate 220 is in contact with the interior of the warehouse filled with cold air, water vapor may condense due to a temperature difference between the upper and lower spaces and the interior of the warehouse, resulting in dew. If there is moisture in the upper and lower spaces, the upper and lower spaces are contaminated or there is a risk of safety accidents due to slippery work. Therefore, the second gate 220 needs to be made of an insulating material. To this end, the second gate 220 may have a reflective plate on a surface facing the interior of the warehouse, and an air pocket insulation material is provided on a surface facing the upper and lower spaces to be configured as a double layer.

Referring to FIG. 4, an air curtain may be formed in the upper and lower spaces by the air curtain forming part 300. Air is sprayed from the air curtain forming part 300 installed in the upper frame 110 toward the lower frame 150 to prevent the cold air inside the warehouse from leaking to the outside and prevent pollutants from entering the warehouse. have. After the injected air is introduced into the lower frame 150, the upper and lower spaces may be continuously circulated through the inside of the side frame 130. In order to circulate air, a duct (not shown) through which air can flow through a combination frame or an upper and lower space may be provided inside the lower frame 150 and the side frame 130.

5 is a side cross-sectional view of the dock shelter module according to the first embodiment of the present invention.

The upper frame 110 may be formed with an air curtain forming unit 300 of the warehouse and an upper flow path 320 communicating with the inside and outside of the warehouse. The upper flow path 320 is a path through which air supplied to the air curtain is introduced, and an upper valve 310 may be provided to selectively control the air inflow as necessary.

In the dock shelter module 10 according to the first embodiment of the present invention, cold air is injected to maintain the temperature inside the warehouse during the loading and unloading process, and after the loading and unloading work is completed, in order to dry the up and down space It can be configured to spray warm air. To this end, the upper flow path 320 may include an upper first flow path 321, an upper second flow path 322, and an upper third flow path 323.

Among the upper flow paths 320, the upper first flow path 321 has one end connected to the inside of the warehouse and the other end connected to the upper valve 310, and the upper second flow path 322 has one end connected to the outside of the warehouse and the other end. Is connected to the upper valve 310, and the upper third flow path 323 may be configured to be connected to the air curtain forming part 300 at one end and to the upper valve 310 at the other end.

This will be described in detail with reference to FIG. 5. When the first gate 210 and the second gate 220 are opened for the up and down operation, the air curtain forming unit 300 is actuated to form an air curtain. In this case, the air injected from the air curtain forming unit 300 may be injected with cold air using the cold air inside the warehouse. When the cold air inside the warehouse flows into the upper first flow channel 321 and then the upper valve 310 is set to pass through the upper third flow channel 323, the air curtain forming unit ( 300). Therefore, in the process of lifting and lowering by opening the first and

second gates

210 and 220, the cold air is injected into the air curtain forming unit 300, so that the cold air is injected to form an air curtain. This not only prevents the loss of cold air inside the warehouse, but also does not require a device such as a separate compressor for forming cold air, so the structure is simple and the cost is low.

When the lifting operation is completed and the first gate 210 and the second gate 220 start to be closed, the air introduced into the air curtain forming unit 300 is changed to air outside the warehouse. To this end, the upper valve 310 is set so that the second flow path connected to the outside of the warehouse is connected to the third flow path. When air from outside the warehouse flows into the upper second flow passage 322 and flows through the upper third flow passage 323 to the air curtain forming unit 300, warm air may be injected from the air curtain forming unit 300. Although not shown in the drawing, a heating device may be separately provided in the upper frame 110 so that the temperature of the incoming air is increased and sprayed.

If the upper and lower spaces are closed after the cold wind is blown during the loading and unloading process, condensation may occur due to condensation of the cold air in the upper and lower spaces.Therefore, the upper and lower spaces may be contaminated or a safety accident may occur during the subsequent loading and unloading process. Because there is, it is possible to dry the upper and lower spaces by spraying warm air.

Further, as shown in FIG. 5, a lower flow path 340 may be formed in the lower frame 150 as well. The lower flow path 340 serves to allow the air injected from the air curtain forming unit 300 to flow in and circulate. A lower valve 330 for selectively controlling the flow of air may be provided in the lower flow path 340.

The lower flow path 340 has one end connected to the inside of the warehouse, the other end connected to the lower valve 330, the lower first flow path 341, one end connected to the outside of the warehouse, and the other end connected to the lower valve 330. The lower second flow path 342, one end connected to the bottom of the lower frame 150, and the other end may be composed of a lower third flow path 343 connected to the lower valve 330.

When cold air is injected from the air curtain forming unit 300 during the up and down operation, it flows to the lower frame 150 and flows into the lower third flow path 343 connected to the lower frame 150. Air introduced into the lower third flow path 343 flows to the lower valve 330. When the first and

second gates

210 and 220 are open, the lower valve 330 is set so that the lower third flow path 343 and the lower first flow path 341 communicate. Accordingly, the introduced air may flow into the lower first flow path 341 and be discharged back into the warehouse.

When the lifting operation is completed, warm air is injected from the air curtain forming unit 300 and flows into the lower third flow path 343. At this time, the lower valve 330 is set so that the lower third flow passage 343 and the lower second flow passage 342 communicate. Accordingly, the introduced air flows into the lower second flow path 342 and is discharged to the outside of the warehouse.

Since the lower flow path 340 is formed, the air injected from the air curtain forming unit 300 can be smoothly circulated, thereby preventing the outflow of cold air inside the warehouse and the inflow of external pollutants.

On the other hand, although not shown in the drawings, the upper flow path 320 and the lower flow path 340 may further include a blower fan that facilitates the flow of air to facilitate the inflow and discharge of air.
